SPECIFICATION forming part of Letters Patent No. 769,018, dated August 30, 1904.

Application filed February 9,1904. Serial No. 192,857- (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM PERSON, a citizen of the United States, residing at Rockford, in the county of Winnebago. and State of Illinois, have invented certain new and useful Improvements in Sewing-Machine Cabinets, of which the following is a specification.

The objectof this invention is to construct a sewing-machine cabinet in which the plat-' Fig. 2, in which the platform is lowered. Fig. 7

5 is a section on dotted. line b, Fig. 2. Fig. 6 is a section on dotted line 0, Fig. 2. f

The cabinet-top 1 is supported by the sides 2 and back 3. The frame 4 is secured to the top and has an opening to the rear side of which is hinged a platform 5 in a manner that it may drop. To the platform is hinged a platform extension 6. A roller 7 is pivotally connectedto the rear wall of thecabinet near the end at which the cover is hinged. To the back of the cabinet are secured two brackets 8 near the ends of the cabinet. A bracket 9 is secured to the back of the cabinet between the brackets 8. The brackets, as shown at Fig.

5, are open on their outer face, and thebracket 9 (shown at Fig. 6) has a central opening 10. A rod 11, with outwardly-turned arms 12, is located in the three brackets and held from displacement by the center bracket 9. To the free end of each of thearms 12 is pivoted a link 13, and the other ends of these links are pivotally connected to the under face of the platform 5 near its ends.

To the rod 11 is secured a segmental gear 14. From the bracket 9 extends a stud 15, which supports a toothed quadrant 16, which meshes with the segmental gearv 14. From the toothed quadrant extends" an arm 17, to

the free end of which is connected a band 18, passing over the roller 7 and connected to the cover 19 at the point 20. The connection of the band 18 with the arm 17 is made adjustable by the threaded rod 21 and nuts 22, placed on either side of the arm, by means of which the proper length may be given to the connection. From the toothed quadrant 16 the parts'are in' the position shown at Fig. 4

the platform is dropped into the cabinet and the cover closed over the top. Upon opening the cover the toothed quadrant will be rocked on its pivotal support, which will partially revolve the segmental gear, which in turn will rock the rod and cause the arms to raise and straighten the link connection with the plat-- form until the platform is raised into the position shown at Fig. 3, which will bring the platform flush with the upper surface of the frame. When the cover'is being closed, the weight of the sewing-machine headsupported upon the platform-will, through the links and arms, rock the rod and partially rotate the segmental gear, and its return will move the toothed quadrant, which will increase the tension of the coiled spring and prevent the too [sudden descent of the machine-head. The coiled spring will assist in raising the plat- {form and sewing-machine head supported thereby. The brackets 8serve to hold the ends of the rod in line with the center bearing and also prevent endwise movement of the rod.
